Measurement of the Bs-Bsbar Oscillation Frequency

CDF Collaboration

We present the first measurement of the Bs-Bsbar oscillation frequency Delta m_s. We use 1 fb^-1 of data from p-pbar collisions at sqrt{s}=1.96 TeV collected with the CDF II detect…

Measurement of the Ratio of Branching Fractions B(D0 -> K+ pi-)/B(D0 -> K- pi+) using the CDF II Detector

CDF Collaboration, A. Abulencia

We present a measurement of R_B, the ratio of the branching fraction for the rare decay D0 -> K+ pi- to that for the Cabibbo-favored decay D0 -> K- pi+. Charge conjugate decays are…

Top Quark Mass Measurement from Dilepton Events at CDF II with the Matrix-Element Method

A. Abulencia

We describe a measurement of the top quark mass using events with two charged leptons collected by the CDF II detector from collisions with TeV at the F…

Observation of Bs to Psi(2S)phi and Measurement of Ratio of Branching Fractions B (Bs --> Psi(2S)phi) / B (Bs --> J/Psi phi)

CDF Collaboration, A. Abulencia

We report the first observation of Bs to Psi(2S) phi signals using 360 pb^-1 of CDF Run II data sample, where Psi(2S) decays into mu+mu- and J/psi pi+pi- modes with phi decays to K…

Measurement of the Helicity of W Bosons in Top-Quark Decays

A. Abulencia

We measure the branching fraction of the top quark to longitudinally and right-handed polarized bosons, and , using approximately 200 pb of collisi…

Search for Bs -> mu+mu- and Bd -> mu+mu- Decays in ppbar Collisions with CDF II

The CDF Collaboration

We report on a search for Bs -> mu+mu- and Bd -> mu+mu- decays in ppbar collisions at sqrt(S) = 1.96 TeV using 364 pb-1 of data collected by the CDF II detector at the Fermilab Tev…
